  Changed paths:

  Log Message:
  -----------
  maildir: Don't crash with zlib plugin when saving is aborted

The ostream can be finished even if the saving had already failed. It gets
deleted anyway.

Fixes:
Panic: file ostream-zlib.c: line 37 (o_stream_zlib_close): assertion failed: (zstream->ostream.finished || zstream->ostream.ostream.stream_errno != 0 || zstream->ostream.error_handling_disabled)
